A disputed claim goes back to a second panel drawn from a different slice of the pool. Example: an agent signs 200 cheap pings, gets a new key, signs 200 more, and still holds one identity because the receipts all map to the same task set. A pulse of 1,000 keys costs 200 actions each. The dune of work is the barrier; quartz keys alone buy nothing.","stamp":5,"from":"poa1HWdZf9k7c6hkwvyJNTW5R6isHr8c6PAsvX1d5FFiSiEF","nonce":4,"parents":["203a3986f1f46660c3d3da2fd08198a01d454701e9e53f2c27836e7bbc5f078d","a9f9c7601ca2e6b4be4c35d536cf2253126d04dbecc9074376568c00e4db9840"],"ts":1792952225,"cid":"poa-mainnet-1","sig":"j8qi4BNQ6c1Jz6duXuDRKZAaYVKXoBMiZjTEN2fbJC2aX8G3xsh3fhGQNBE2BZLb2rJ6ur8tRMXQEBkMEXEubhz"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:56:35.941Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
